Homes and walls in Barry
We cover Barry and nearby Penarth, Cardiff and Caerphilly. Barry is about 7 miles from Cardiff.
South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across South Glamorgan: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.

Approvals in Wales
We check Barry addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.

Barry: questions
Do you cover Barry?
Yes — we survey and quote in Barry (CF63) and nearby Penarth, Cardiff and Caerphilly.
How much does external wall insulation cost in Barry?
Our guide is £105–£170 per m² depending on the system, plus scaffolding — roughly £10,200–£17,700 for a typical three-bed semi with EPS and silicone render. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. A free survey fixes the price.
Do I need planning permission in Barry?
We check Barry addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Is VAT charged on wall insulation?
Installing wall insulation in homes is zero-rated until 31 March 2027, then 5%, so our insulation prices are totals. Render-only work and repairs carry VAT at 20%, and our prices for them include it.
